Last change on this file since b27557b was a73e91a, checked in by Wilmer van der Gaast <wilmer@…>, at 2008-02-16T17:38:30Z
Added callback on Jabber add-to-roster requests so buddies get added to the internal buddy list a little bit earlier. This should deal better with Jabber servers that send presence information of a new buddy before the roster push.
Property mode set to `100644`
